Definitions

  • the present invention relates to a variable-wheel-gage bogie capable of continuously varying its wheel-back-gage to run continuously on railroad tracks respectively of different railroad gages, such as the railroad tracks of the Shinkansen railroad and the railroad tracks of the conventional Japanese railroads. More specifically, the present invention relates to an improved variable-wheel-gage bogie for rolling stock, having a locking mechanism for locking a wheel supporting mechanism in place so that a wheel supported thereon cannot be axially moved for wheel-back-gage change, capable of being surely engaged and disengaged.
  • Japanese railroad tracks include a standard-gage track of a railroad gage of 1435 mm, which is used for the Shinkansen railroads, and a narrow-gage track of a railroad gage of 1067 mm, which is used for the conventional railroads.
  • Development of rolling stock capable of continuously running on the railroad tracks respectively having the different railroad gages will provide very important advantageous effects on the convenience of passengers, and the reduction of time necessary for traveling to destinations and railroad construction costs.
  • the applicant of the present invention patent application developed various variable-wheel-gage bogies for rolling stock and filed applications for patent previously.
  • variable-wheel-gage bogie shown in Fig. 16 has a plurality of wheels 4 and associated mechanisms. Only one of the wheels 4 and the associated mechanism will be described because all the wheels 4 and the associated mechanisms are the same.
  • An axle 2 is supported for vertical movement relative to a journal box beam 1 and a axle sleeve 3 is put on the axle 2 so as to be axially slidable.
  • the wheel 4 is supported for rotation on bearings, not shown, put on the axle sleeve 3.
  • a locking block 5 is fixed to one end part of the axle sleeve 3.
  • the locking block 5 is provided on its upper surface with a pair of locking projections 6 and 7 spaced a predetermined distance apart from each other in the direction of the axis of the axle 2.
  • the journal box beam 1 is provided with a locking opening 8 in which the locking projection 6 or 7 engages and an escape opening 9.

  • a wheel 4 included in a railroad vehicle supported on the variable-wheel-gage bogie rolls on a downward slope section of a rail 13. Consequently, the wheel 4 moves gradually downward relative to the horizontal body support rail 11, the axle 2 descends relative to the journal box beam 1 and the locking projection 6 is disengaged from the locking opening 8, so that the axle sleeve 3 is able to move along the axle 2. Then, the axle sleeve 3 is moved outward, i.e., to the left as viewed in Fig. 16, to set the wheel 4 at the position for the standard-gage track.
  • axle sleeve 3 supporting the wheel 4 is locked at the position for the standard-gage track.
  • the axle 2 must move vertically relative to the journal box beam 1 when changing the positions of the wheels 4 of this variable-wheel-gage bogie and hence the journal box beam 1 inevitably has a big vertical dimension.
  • variable-wheel-gage bogie shown in Fig. 17 can be changed without vertically moving an axle 2 relative to a journal box beam 1
  • an axle sleeve 3 is axially slidably put on the axle 2.
  • a locking block 5 is put on the axle sleeve 3 for movement together with the axle sleeve 3.
  • the locking block 5 is fitted axially slidably in a cylindrical bore la formed in the journal box beam 1.
  • a locking lever 15 is supported for turning by a shaft 14 on the journal box beam 1 and is biased counterclockwise by a compression coil spring 16. Normally, the locking lever 15 is in engagement with a locking projection 5a projecting from a lower end part of a locking block 5.
  • the locking block 5 is connected to the journal box beam 1 by the locking lever 15, the axle sleeve 3 is unable to move axially on the axle 2 and hence the wheel 4 is locked to inhibit the change of the wheel-back-gage.
  • a sled 10 rides support rollers 12 supported on a body support rail to change the wheel-back-gage, the sled 10 is turned to a horizontal position as shown in Fig. 17 and, at the same time, a link 17 turns the locking lever 15 clockwise on the shaft 14 to disengage the locking lever 15 from the locking projection 5a. Consequently, the axle sleeve 3 can move axially on the axle 2 for wheel-back-gage change.
  • the locking lever 15 starts turning in an unlocking direction, i.e., a clockwise direction as viewed in Fig. 17, simultaneously with the start of turning of the sled 10 toward the horizontal position upon the engagement of the sled 10 with the first one of the support rollers 12 supported on the body support rail.
  • the locking lever 15 starts turning in a locking direction, i.e., a counterclockwise direction as viewed in Fig. 17, simultaneously with the start of the sled 10 leaving the last one of the support rollers 12.

  • a variable-wheel-gage bogie for rolling stock comprises: axles; a drive motor mounted on a truck frame; a reduction gear for transmitting output rotative driving force of the drive motor to the axle and reducing an input speed to a lower output speed; right and left journal box beams connected to the truck frame and to right and left axle end beams supported on thrust bearings mounted on opposite ends of the axle, respectively; right and left journal boxes fitted in the right and the left journal box beam, respectively, so as to be slidable along an axis of the axle relative to the journal box beams, respectively; right and left axle sleeves supported in axle bearings on the pair of journal boxes, respectively, and put on the axle; right and left wheels mounted on the right and the left axle sleeve for rotation together with the right and the left axle sleeve, respectively; a rotative driving force transmitting means interlocking each axle sleeve and the axle to transmit rotative driving force from the axle to the axle sleeve; and locking
  • journal box beam has a small vertical dimension.
  • the locking mechanism that locks the journal box so that the wheel cannot move axially for wheel-back-gage change is not operated by the body weight-bearing rail that engages the journal box beam but the same is disengaged by the first operating means independent of the body support rail.
  • the locking mechanism can be disengaged for an unlocking operation after the journal box has been supported on the body support rail and the body weight has been removed from the axle and therefore the locking mechanism that restrains the wheel from axial movement to inhibit wheel-back-gage change can be surely disengaged.
  • variable-wheel-gage bogie it is preferable that the locking member is returned to the locking position by a second operating means disposed beside the body support rail when the locking member does not return to the locking position after a wheel-back-gage changing operation has been completed. Since the locking mechanism is operated while the journal box is supported on the body weight-bearing rail and the axle is not loaded with the body weight, the locking mechanism can be surely and smoothly engaged so that the wheel-back-gage cannot be changed.

  • a part of the axle close to the wheel can be surely covered for protection and the outer end part of the dust cover on the side of the wheel can be supported with reliability.
